Extraction by a surfactant-rich, water-immiscible phase formed by adding a dehydrating agent to a colloidal solution of the sample and a surfactant above its critical micelle concentration.
Note: In cloud point extraction a small volume "surfactant-rich" phase enriched in sample components of moderate water solubility and a bulk aqueous phase with dissolved surfactant and highly water-soluble compounds are formed.
